Rigorous Science

Would the sudden creation of a super-suit cause noticeable wind?

+0
−0

Using my world changing invention and my massive intellect I have created the perfect defensive tool for myself and any minions valued friends I deem might need one.

The tool is a super suit that doesn't actually exist until it's needed. The suit is worn as a bracelet, and when activated the bracelet will take all the air (and clothing) in it's immediate vicinity and start to transmute it (in a lossless way, including all binding/rest energies) into the metallic components of the suit, rapidly expanding outwards over the user's body. The growth rate of the suit over the person is exponential as more air becomes available to transmute. Once the suit is fully complete the wearer will be practically impervious to all known weaponry, not to mention super strong, super fast and equipped with fully operational life support.

The question is this: Given that the materials that make up the suit are roughly equivalent to 20 kg of iron: How much air is required to make the suit, and will this cause an appreciable gust of wind if the suit is applied at maximum speed at sea level? For bonus points work out what the maximum speed is.

For the sake of simplicity clothing doesn't add any appreciable energy to the equation (assume everybody is buck naked).

A quick note: While the premise of the question isn't hard, equations/workings are needed for this one, hence the 'hard-science' tag rather than 'science based'.
